Application filed February 23, 1909. Serial No. 479,464.

To all whom 'it may concern:

Be it known that I, WILLIAM B. CoGGER, a citizen of the United States ofAmerica, residing at Cleveland, in t-he county of' Cuyahoga and State ofOhio, have invented certain new and useful Improvements inVertically-Adjustable Supports; and I hereby declare the following to bea full, clear, and exactdescription of the invention, such as willenable others skilled in the artto which it pertains to make and use thesame.

This invention relates to improvements in supporting structures forobjects, such, for instance, as desks, tables and seats which areadjustable up and down.

The primary object of this invention isj to provide a supportingstructure compris-j the adjusting mechanism and is borne by armsdepending from and rigid with the aforesaid adjustable object, but tolaterally space and brace apart the said arms by a bar which covers andprotectsthe shaft between the said arms' without occupying muchl space.

Another object is to hold the said bar to the said arms withoutnecessitating the use the other at the inner side of the other of downrelative to the said supports. Fig. 2 is a vertical section on line 'Q-2, Eig. 1, looking in the direction indicated y the arrow. Fig. 3 is avertical section'von line 3 3, Fig. 2, looking inthe direction mdrl,supports.

cated by the arrow. Fig. 4 is a verticalsection on line 4 4, Fig. 2,looking inwardly,

except that the nut employed in securing the adjustable object in thedesired adjustment is shown turned in Fig. 4 to bring the slots orrecesses in the periphery'of the nut into registry with the slots orrecesses in the periphery of a collar interposed between-the said nutand the adjacent standard or support. Fig. 5 is a vertical section online 5 5, Fig. 2, looking outwardly. Fig. 6 is a horizontal section online 6 6, Fig. 2, looking downwardly. Fig. 2 is drawn on a larger scalethan Fig. l, and Figs. 3, 4, '5 and 6 are drawn on a larger scale thanFig. 2. Portions are vbroken away in Figs. 2 and 6 to' reduce the sizeof the said figures.

In the said drawings, A and A indicate two laterally spaced standards orsupports which are rendered stationary in any approved manner and areadapted to be se cured to a floor or base (not shown). Each support A isprovided with a slot a which extends up and down the said support.

A horizontally arranged shaft B extends between and through the supportsA, projecting or extending at the ends through -the slots a in thesaid'supports and a suitable distance beyond "the outer sides of thesaid The shaft B is provided externally with Va groove I; which extendsfrom endv to end of the shaft. The shaft 'B extends loosely throughholes e formed in two laterally spaced arms E which depend from and arerigid with the desk or object G which is adjustable up and down on thesupports A. The shaft B bears the arms E and consequently the saidadjustable object G. The arms E are arranged, one at the inner side ofone of the supports A, and

the said supports.

The supports A are provided at the side edges of'the arms E with ribs orguiding members A which extend up and down the said supports and arearranged to guide the said arms during any readjustment of theadjustable object G.

The slotted portion of each support A is offset outwardly, as at A2, toaccommodate the location and operation, between the said portion of thesaid support and the outer side of the adjacent arm F, of a pinion Hwhich is operatively mounted on the shaft B. The operative connectionbetween the 10on y 'groove to the last-mentioned extremity -of l theshaft from the said shoulder also facilitates the assemblage of theparts.

1. The combination, with two laterally spaced standards or supportsprovided each with a slot extending up and down the said support; anobject which is adjustable up and down relative to the said supports,said adjustable object beingprovided with two laterally spaced andsuitably guided depending arms arranged at the inner sides of the saidsupports; a shaft extending between and through and supporting the saidarms and also extending through the slots in the said supports; meanswhereby the shaft is raised or lowered according as the' shaft is turnedin the one or the other direction, and

means whereby the shaft is secured in the desired adjustment, of a barextending longitudinally of the shaft between the arms, said bar beingprovided with a slot which receives the shaft and extendslongitudinallyI of the bar, and members projecting into the said slot inthe bar and rigid with the said llIllS.

2'. The combination, with two laterally spaced standards orv supportsprovided each with a slot extending up and down the said support; anobject which is adjustable up and down relative to the said supports,said adjustable object being provide with two v laterally spaced andsuitablyv guided depending arms arranged at the inner sides of the saidsupports a shaft extending between and through and supporting the saidarms and also extending through the slots in the said supports; meanswhereby the shaft is raised or lowered according as the shaft is turnedin the one or the otherdirection, and means whereby the shaft is securedin the desired adjustment, of a bar extending longitudinally of theshaft between the arms,

said barbeing provided with a slot which extends longitudinally of thebar and having such arrangement relative to the shaft that the latterextends through the lastmentioned slot, and flanges formed on the armsand extending circumferentially of the ends of the bar, said flangesbeing provided internallyY with lugs projecting into the lastmentionedslot. y In testimony whereof, I sign the foregoing specification, in thepresence of two witnesses.
